Steve Martin wrote and stars in this look at the promise and dreamtime of Los Angeles culture. Martin stars as Harris K. Telemacher, a light-hearted television weatherman who does wacky comedy in lieu of reports since, being in L.A., he has very little weather to report. He spends his time roller-skating through museums and spending time with California's beautiful people. But Telemacher is fired and discovers that his girlfriend Trudi (Marilu Henner) is having an affair. He walks away from the relationship and re-evaluates his life, getting advice from a friendly electronic highway road sign. The sign suggests that he call SanDeE (Sarah Jessica Parker), a sprightly and attractive Valley Girl he met in a clothing store. With SanDeE he experiences a liberating and carefree spirit. But Telemacher comes to realize that he has actually fallen in love with Sara (Victoria Tennant), a tuba-playing British journalist who is in California to do a feature on Los Angeles lifestyles.
